Description

[0002] Production management refers to the optimization of production plans and process arrangements through advanced scheduling algorithms, lean production concepts and real-time monitoring, and the improvement of material storage and handling efficiency through warehouse management, distribution route optimization and automated equipment. It also uses scheduling algorithms, machine learning and predictive analysis techniques to optimize process arrangements and logistics distribution, as well as information integration and supply chain management systems to achieve coordinated optimization of all aspects of production, logistics and supply chain.

[0038] Figure 1 The following schematically shows a flow chart of a material distribution method according to an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a material distribution method, which is applied to a production workshop. The production workshop includes multiple workstations. The method may include the following steps.

[0039] Step 101, after obtaining the order to be produced, generate a production schedule for the order to be produced, the production schedule at least includes the start time of each process to complete the order to be produced, the work station required to complete each process, the multiple materials required for each process and the first material quantity of each material.

[0040] In the embodiment of the present application, it should be noted that the order to be produced can refer to the batch production of a certain model and specification of products. Under normal circumstances, the production of a finished product of a product requires several processes, and the processes included in products of different models and specifications are different. At the same time, due to the inconsistency of the processing technology of different processes and the different processing time required for each process, the reasonable arrangement of each process can effectively improve the production quality and production efficiency of the product. Therefore, in the present technical scheme, after obtaining the order to be produced, in order to be able to complete the order to be produced with high quality and high efficiency within the deadline for delivery, multiple constraints such as workshop production capacity, station equipment availability and human resources can be considered, and according to the production plan and the dependency between processes, the process-level production of the production order to be produced is scheduled to generate a corresponding production schedule. Among them, the production schedule should include the start time of each process to complete the order to be produced, the station required to complete each process, the multiple materials required for each process, and the first material quantity of each material. It should be noted that the production workshop includes many types of workstations. Different types of workstations can perform different processes due to the different types of equipment installed. For example, a production order includes process A, process B, process C and process D. Assuming that the equipment installed at a certain workstation is a punching machine, and the processes involving punching are process A and process D, then the processes that can be processed at this workstation are process A and process D. Therefore, the production schedule should include the workstations required to complete each process.

[0041] In one embodiment, after obtaining the orders to be produced, generating a production schedule for the orders to be produced includes: constructing a digital model for the production workshop; determining the constraints that affect the production workshop's completion of the production orders, the constraints including at least one of process priority constraints, combined process constraints, workstation equipment mold change constraints, workstation equipment capacity constraints, material resource constraints, balanced production constraints, and outsourced process constraints; after obtaining the orders to be produced, determining the production data of the production workshop and the order data of the orders to be produced, wherein the production data includes at least the equipment status of each workstation in the production workshop and the worker scheduling data, and the order data includes at least the product process route of the orders to be produced and the materials required for the products; generating a production schedule for the orders to be produced based on the constraints, production data, and order data through the digital model.

[0042] In this embodiment, after obtaining the order to be produced, the production workshop can be abstractly modeled based on the principle of mathematical programming, and a digital model for the production workshop can be constructed to convert the actual business model into a mathematical model, wherein the station equipment needs to be considered in the workshop modeling, and the order and process need to be considered in the input modeling. Analyze and extract the constraints that affect the production workshop to complete the production order, and the constraints include process priority constraints, combined process constraints, station equipment mold change constraints, station equipment capacity constraints, material resource constraints, balanced production constraints, and outsourcing process constraints. At the same time, after obtaining the order to be produced, determine the production data of the production workshop and the order data of the order to be produced, wherein the production data should include the equipment status of each station in the production workshop and the worker scheduling data, and the order data should include the product process route of the order to be produced and the materials required for the product. The constraints are converted into algorithmic constraints corresponding to the digital model, so that the production schedule for the order to be produced is generated based on the constraints, production data, and order data through the digital model.

[0043] Step 102, sorting the multiple processes based on the start time of each process, and determining the delivery batches of the multiple processes based on a preset delivery cycle.

[0044] In an embodiment of the present application, after the start time of each process is obtained based on the production schedule of the order to be produced, multiple processes are sorted based on the development order of the start time. It should be noted that, under normal circumstances, the material distribution method of the production workshop is batch distribution, that is, a large amount of materials are distributed at one time. For each process, the number of materials required for each process is much smaller than the single-time distribution quantity of the production workshop. Therefore, in order to optimize logistics resources, the material requirements of several processes can be merged for batch distribution, that is, the multiple processes after the sorting of the order to be produced are divided into multiple distribution batches based on the preset delivery cycle, and each distribution batch only distributes the material requirements of several processes, and the distribution batches are divided into the first distribution batch, the second distribution batch, and the first distribution batch according to the development order of time. It should be noted that the preset delivery cycle can be set according to the actual production demand, for example, it can include but is not limited to one month, three months, and a batch distribution of materials is carried out every preset delivery cycle.

[0045] Step 103, for any workstation, determine the number of starts of the workstation in each preset delivery cycle, the type of materials required for each start, and the quantity of the second material required for each material, so as to determine the type of materials and the required quantity of materials required by the workstation in each preset delivery cycle.

[0046] In the embodiment of the present application, it should be noted that the production schedule has determined the workstations required to complete each process, the multiple materials required for each process, and the first material quantity of each material. Therefore, after determining the delivery batches of multiple processes based on the preset delivery cycle, for any workstation, it is necessary to first determine the number of times the workstation is started in each preset delivery cycle, the type of materials required for each start, and the second material quantity required for each material, so as to further determine the type of materials and material demand quantity required by the workstation in each preset delivery cycle. For example, take a workstation that processes process A and process B within a preset delivery cycle as an example. Assume that the workstation needs 1 material a, 3 materials b, and 2 materials c to process each unit product of process A, and needs 1 material a, 3 materials b, and 4 materials c to process each unit product of process B, and the workstation processes a total of 100 times within the preset delivery cycle. It can be seen that the types of materials required by the workstation within the preset delivery cycle include material a, material b, and material c, and the number of materials required is ((1+1)+(3+3)+(2+4))×100=140. It should be noted that for any workstation, usually because the type of equipment used for processing at the workstation is fixed, the processing actions that can be performed by the workstation when processing each unit product of any process should be the same, that is, the types of materials required should be the same.

[0047] In one embodiment, the method further includes determining a delivery batch corresponding to any material delivered to any workstation according to formula (3):

[0048] (3),

[0049] in, The duration corresponding to any preset delivery cycle, is the delivery batch corresponding to the i-th material delivered to workstation k, is the quantity of the i-th material required by station k to process each unit of product in any process in any delivery batch, The quantity that can be delivered by the production workshop within each preset delivery cycle. is the number of processing times of workstation k within any preset delivery cycle T.

[0050] In this embodiment, The final value of should be an integer. Express The calculated result is rounded up.

[0051] Step 104 , determining the types of materials and the total quantity of material requirements required by all workstations in each preset delivery cycle according to the types of materials and the quantity of material requirements required by each workstation in each preset delivery cycle.

[0052] In an embodiment of the present application, for any preset delivery cycle, after obtaining the types of materials and the required quantity of materials for each workstation within the preset delivery cycle based on the number of times each workstation starts work within the preset delivery cycle, the types of materials required for each start-up, and the quantity of the second material required for each material, the types of materials and the total required quantity of materials for all workstations within the preset delivery cycle can be further determined.

[0053] Step 105 , based on the deliverable quantity in each preset delivery cycle, the material types and the total material demand quantity required by all workstations in each preset delivery cycle, determine the material types and the delivery quantity of each material in each delivery batch.

[0054] In an embodiment of the present application, after determining the types of materials and the total number of material requirements required by all workstations in each preset delivery cycle, the types of materials to be delivered in each delivery batch and the delivery quantity of each material can be further calculated based on the deliverable quantity in each preset delivery cycle and the types of materials and the total number of material requirements required by all workstations in each preset delivery cycle. It should be noted that each delivery batch is a unified delivery that combines the needs of several processes, and the quantity that can be delivered in each delivery batch is fixed. Therefore, there may be several processes whose demand quantities are higher than the quantity that can be delivered in each delivery batch. At this time, the quantity that can be delivered in each delivery batch should be used as the delivery standard, and the order of arrangement of the several processes should be used as the order of material requirements, so that the materials delivered in the current batch will give priority to the processes with a higher order.

[0055] In one embodiment, for any workstation to which materials need to be delivered in any delivery batch, the method further includes: determining the types of materials that can be delivered by the workstation in the delivery batch and the deliverable quantity of each material based on the types of materials delivered in the delivery batch and the deliverable quantity of each material, and determining the number of processes for the workstation that can be satisfied by the types of materials that can be delivered and the deliverable quantity of each material; for any deliverable material in the delivery batch for the workstation, determining the transportation time required to transport the material from the storage location to a preset storage location in the production workshop, and determining the target delivery time of the material for each process in the delivery batch based on the transportation time and the start time of each process corresponding to the material in the delivery batch; and determining the earliest target delivery time among multiple target delivery times as the delivery time of all deliverable materials of the workstation in the delivery batch.

[0056] In this embodiment, it should be noted that after determining the types and quantities of materials to be delivered in each delivery batch, it is necessary to further determine the optimal delivery time of the delivery batch so that the materials can arrive at each workstation on time and ensure that each process can be processed on time. Specifically, for any workstation to which materials need to be delivered in any delivery batch, since the arrangement order of each process in the delivery batch has been determined according to the development order of time, and the deliverable quantity in the delivery batch is fixed. Therefore, based on the types of materials delivered in the delivery batch and the delivery quantity of each material, the types of materials that can be delivered in the delivery batch and the deliverable quantity of each material can be determined for the workstation, so as to further determine the number of processes for the workstation that can be satisfied by the types of materials that can be delivered and the deliverable quantity of each material, that is, to calculate the material requirements of the process at the workstation that can be satisfied by the materials delivered to the workstation in the delivery batch.

[0057] In this embodiment, it should be noted that for each material, the material needs to be provided by the supplier and transported to the production workshop. Therefore, the storage location may refer to the warehouse location of each material in the corresponding supplier, and the preset storage location may refer to the warehouse location used by the production workshop to store each material. After calculating that the material delivered to the workstation in the delivery batch can meet the material requirements of the process at the workstation, for any deliverable material of the workstation in the delivery batch, it is necessary to first determine the transportation time required for the material to be transported from the storage location to the preset storage location of the production workshop. Specifically, it can be calculated according to the following formula:

[0058] ,

[0059] in, is the transportation time required for the i-th material to be transported from the storage location to the preset location j in the production workshop, is the transportation distance from the i-th storage location to the preset location j of the production workshop, is the average transportation speed of the i-th material, is the loading and unloading time of the i-th material.

[0060] In this embodiment, after calculating the transportation time of the material, the target delivery time of the material for each process in the delivery batch can be further determined based on the transportation time and the start time of each process corresponding to the material in the delivery batch. Specifically, it can be calculated according to the following formula:

[0061] ,

[0062] in, is the target delivery time for each process of the i-th material in the corresponding delivery batch, is the start time of any process j corresponding to the i-th material in the delivery batch, It is the transportation time required for the i-th material to be transported from the storage location to the preset location in the production workshop.

[0063] In this embodiment, it should be noted that since each delivery batch is a batch delivery of material requirements for several processes, and the start time of each process is inconsistent, in order to ensure that each process can start on time, advance delivery should be arranged. Specifically, after calculating the target delivery time of the material for each process in the delivery batch, the earliest target delivery time among multiple target delivery times is determined as the delivery time of all deliverable materials of the workstation in the delivery batch.

[0064] In one embodiment, for any workstation to which materials need to be delivered in any delivery batch, the number of processes that can be satisfied by the workstation in the delivery batch is determined according to formula (1):

[0065] (1),

[0066] in, For workstation k in the The number of operations that can be satisfied when material i is delivered in the delivery batch, , is the quantity of the i-th material required by station k to process the product of any process in any delivery batch, The quantity that can be delivered by the production workshop within each preset delivery cycle.

[0067] In one embodiment, for any workstation that needs to deliver materials in any delivery batch, the delivery time of all deliverable materials in the delivery batch of the workstation is determined according to formula (2):

[0068] (2),

[0069] in, For workstation k in the The time when material i is delivered in the delivery batch, For workstation k in the The earliest target outbound time corresponding to the material i being delivered in the delivery batch, For workstation k in the The order of the process corresponding to the earliest target delivery time of material i in the delivery batch among all the processes of the production order to be produced, For workstation k in the The number of operations that can be satisfied when material i is delivered in the delivery batch, .

[0070] In one embodiment, for any workstation to which materials need to be delivered in any delivery batch, the method further includes: after determining the outbound delivery time of all deliverable materials of the workstation in the delivery batch, for any deliverable material of the workstation, determining a transportation plan for the material based on the storage location of the material, the transportation route between the storage location and a preset storage location of the production workshop, the status of the transportation vehicle, and the outbound delivery time; based on the transportation plan, ensuring that the material can meet the outbound delivery time of the workstation in the delivery batch, wherein the transportation plan includes the optimal transportation route and arrival time.

[0071] In this embodiment, it should be noted that in order to ensure that the materials can arrive at the warehouse of the production workshop on time, a reasonable transportation plan should be formulated. Specifically, after determining the outbound time of all the deliverable materials of the workstation in the delivery batch, for any deliverable material of the workstation, the transportation plan for the material, that is, the optimal path and arrival time, is determined based on the storage location of the material, the transportation route between the storage location and the preset storage location of the production workshop, the status of the transportation vehicle, and the outbound time. Among them, the arrival time can be calculated according to the following formula:

[0072] ,

[0073] in, For materials The time when the goods must arrive at the warehouse to ensure on-time delivery after quality inspection and unloading. For materials The time required for quality inspection, It is material The time required for unloading.

[0074] After formulating the transportation plan, ensure that the material can meet the delivery time of the workstation within the distribution batch based on the transportation plan to ensure the on-time arrival of the material.

[0075] The above technical solution, by formulating a production schedule, accurately determines the start time of each process, divides different processes into different distribution batches according to the correspondence between processes and workstations and the arrangement order of processes, and uniformly distributes materials for the processes in the distribution batch. At the same time, based on the correspondence between processes and workstations, the types of materials to be distributed in each distribution batch and the distribution quantity of each material are accurately calculated. It efficiently meets the material distribution needs of complex process processing in the production process, thereby effectively improving the production and management efficiency in the production process.

[0076] This technical solution significantly improves production efficiency and logistics performance through integrated production scheduling, material management and logistics optimization. First, multiple constraints and dependencies between processes are comprehensively considered, and advanced scheduling algorithms are used for optimization to accurately determine the start time of each process. Secondly, by calculating the exact time of material launch and optimizing the distribution path, the solution ensures that materials arrive on time, reducing shortages and backlogs. At the same time, through batch distribution and early arrival strategies, materials are ensured to be in place before production, improving production continuity. Real-time monitoring and dynamic adjustment functions allow for rapid response to changes in production and logistics processes, further improving the accuracy and flexibility of the plan. Overall, this solution has demonstrated significant advantages in reducing logistics costs, improving production efficiency, optimizing material management and enhancing corporate competitiveness, and ultimately improving customer satisfaction.
